USB 3 hub not showing in Ubuntu 18.04

   I have a problem with a usb pci card not being recognised or usable.

The main chip on the usb 3 hub card is a VLI (VL805-06). The card is plugged directly into a pci slot.  

I tested the usb hub cards using usb 2 and 3 devices plugged into them.They were not being recognised. 

I checked via LSUSB and the devices plugged  into the cards were also  not appearing there.

I have  switched the USB settings in the UEFI to auto compatibility and ran the same test as above. The result was negative.

What can I do to make the hub be recognised?

Here are  my MB details:

mb: asrock FM2A88X extreme6+
Serial Number from label on MB's Box: 43MOXD0148/6

Memory: 14.6gb
CPU: AMD A10-4500 Radeon R4
UEFI setup utility:
Switch off  C6 state in advanced-cpu config- core 6 mode
(With C6 on ubuntu crashes)
Serial Number:  43MOXD0148/6
bios version PA.20 from:
bios set to XHCI instead of EHCI
IOMMU disabled
 iommu=soft set as a kernel parameter in /etc/default/grub:
      GRUB_CMDLINE_LINUX_DEFAULT="quiet splash iommu=soft"

	My gut says its more of a Linux kernel/class driver problem than a mobo problem, but I could be wrong. I'm running a hacked version of Ubuntu 18.10 with Cinnamon desktop and some other stuff, and mine sees the built in USB3 with no problem, but the board you're using is older. I'm using the AB350 ITX board with a 200GE at the moment. Not that familiar with the BIOS/firmware settings, but the only hardware problem that it could be is a PCIe setting. The USB settings in BIOS you played with are for onboard USB MACs built into the system, and if I'm not mistaken, it has more to do with runtime behavior for USB booting and kbd/mouse more than anything else. It simply could be that Debian doesn't have any hub driver support in the distribution, and therefore never made it into Ubuntu. SWAG on my part, but wouldn't surprise me.
